Folio

Very simple app to track your stock portfolio. This is not suitable for high-frequency trading, but allows you to monitor the value of your long-term positions. No ads, no account needed, no data collection - all data is stored locally and it only loads prices for stocks you are interested in. US markets only.

Quick start guide:
- Swipe group left to add new positions
- Press and hold, then drag to delete
- Swipe down to refresh

If widgets are used, then data will be refreshed automatically every 30 minutes.
